proxystore11/x-ui-sub-template ? reverse-engineered prompt

Build me a polished subscription page for my X UI panel that looks modern and works out of the box.

I want a single HTML file that shows subscription details in a clean glass style, with dark and light themes, a language switch for English and Persian, and RTL support when Persian is shown. It should include a nice animated usage circle, download and upload stats, total and remaining traffic, and a live remaining time countdown. Add a QR code for the subscription link, easy copy buttons, and quick import links for common clients like V2RayNG and similar apps.

Make it fully responsive for mobile and desktop, and keep it dependency free if possible. If you need anything current from the web, look up the latest docs or examples first. Also include simple install, update, and uninstall scripts so I can drop it into an X UI server easily.
